Abstract

Unlike previous studies that reported the infection rates of Dirofilaria immitis in companion dogs, D. immitis genes were tested directly on mosquitoes to see how many mosquitoes actually carry larvae. Mosquito samples were collected from six parks in Incheon from March to August 2018. A total of 18,589 mosquitoes was collected, classified by type and then made 575 sample pools based on 50 mosquitoes. The PCR method was used to detect Dirofilaria immitis genes of sample pools. Dirofilaria immitis genes were detected in 7 of the 575 pools, and these positive mosquito samples were collected in 4 out of the 6 parks. The types of detected mosquitoes were Aedes dorsalis and Ochlerotatus koreanus which have been identified to act as a vector for heart worm propagation in Incheon. Based on these results, it was concluded that D. immitis genes were found in mosquitoes in the neighborhood park.
